TRUCK-BOLSTER HANGER.

Specification of Letters Patent.

Patented March 17, 1908.

Application filed August 20, 1906. Serial No. 331.349.

To all whom. it may concern.'

Be it known that I, WILLIAM GUNN Pinon, a resident of New Castle, in thecounty ol' Lawrence and State ot Pennsylvania, have invented a new anduseful Improvement in Truck-Bolster Hangers; and l do hereby declare thefollowing to be a full, clear, and eX- act description thereof.

This invention relates to bolster hangers for swing bolster trucks, andthe object ot the invention is to provide a construction ot bolsterhanger wherein the wear that usually takes place is avoided.

The invention consists in the construction and arrangement ot partshereinafter described and claimed.

ln the accompanying drawing Figure 1 is a plan view of a portion of atruck frame showing my invention applied thereto; Fig. 2 is a verticaltransverse section on the line Qui, Fig. 1; 3 is a horizontal sectionthrough the transom, bracket and hanger; and Fig. 4 is a verticalsection through the upper end of the hanger and pin on a plane parallelto the bolster; Fig. 5 is a perspective view of the wearing block.

My invention can be applied to any swing bolster truck, and consequentlythe frame of the truck can be varied within wide limits. ln the drawingsa portion or' the truck side trame is shown at 1 and the transoms at 2.The latter are of angle shape in cross section, as shown in Fig. 2.Riveted to the transoms are the hanger brackets 3, which are locatedinside of the transoms. The hanger is indiiated at 4 and this is theusual U-shape or stirrup form having the upper ends of its limbsprovided with eyes or holes 5 embracing the pins 6 which are fixed inthe transoms and hanger bracket.

One feature ol my improvement consists in thefact that the eyes or holes5 are much larger, and especially much wider than the pins 6, as shownin Fig. 4. Consequently the hanger bears on the pins only at the upperedges of the eyes. The result is that the hanger has a rocking orrolling motion on the pin, Whereas with old constructions wherein theeye is substantially the same size as the pin the eye necessarily had asliding movement circumferentially around the pin as the hanger swung.The old construction subjected both the pin and the hanger to excessivewear which soon loosened and weakened the parts. This is avoided byhaving the eye so'much larger than the pin that contact 1 i l i l l i isonly had at a point, or on a line lengthwise of the pin.

."Lnother feature ol .the invention consists in providing a hard wearingblock or saddle 7 liXcd in a recess S vformed in the hanger at the eye5, this saddle or seat resting upon the pin 6 which also is preferablyof hard steel. The saddle T ma)r be secured in place by any suitablemeans. )is shown, said saddle is provided on its sides with recesses ordepressions i), into which the metal ol' the hanger is'liorced by meansot a punch or the like, thus holding the saddle irmly in place. '.lhissaddle prei:- erably will have a [lat lower tace, or at least onel whichis only slightly rounded so that contact with the pin 6 is only at apoint, or a line, thus giving a more etl'ective rocking movement andmost ell'cctively reducing wear.

The pin 6 may be held against displacement by any suitable means, but asshown in the drawing said pin is provided with a rcduced end portion l()which enters a hole in the transom with the shoulder 1l olE the pinabutting against the inner face ot the transom. The outer end ol' thepin is seated in a hole 12 in the hanger bracket 3. rlhe usual hangerbracket wear plate 14 is secured to the hanger bracket and covers theinner end ot the pin 6, thus keeping the same from displacement. Thiswear plate may be secured in place by any suitable. means, such as thebolts 15 passing through the same and through the hanger bracket.

The construction described is very simple and most etlectively reduceswear at the pivotal point ot the hangers, so that there is not thedanger' ot weakening and loosening the parts as with the old 'form ottruck swing bolster hanger.

That l claim is:

1. ln a truck, the combination ol a frame, and bolster hangers pivotallysuspended from the trame, the pivotal joints comprising pins and eyesconstructed to contact on a line only and the eyes being wider than thepins, thereby producing a rocking movement one on the other.

2. In a truck, the combination ol a lrame, and a bolster hangerpivotally suspended from the trame, the pivotal joints comprising pinssupported by the Al'rame and having rounded upper faces and eyes widerthan the pins and having substantially [lat seats bearing on the roundedVlaces ot said pins.

3. In a truck, the combination of transoms, hanger brackets securedthereto, bolster hangers provided with eyes, pins passing throughopenings in the hanger brackets and the eyes of the hangers and havingreduced ends projecting into the transorns, and wear plates secured tothe brackets and covering the ends of the pins.

4. In a truck, the combination of a frame, and a bolster hangerpivotally suspended from the frame, the pivotal joints of the hangercomprising eyes provided with hardened saddle pieces and hardened 5. Ina truck, the combination of the Jframe, bolster hangers pivotallysuspended from the frame, the pivotal joints of. the hanger comprisingeyes and pins, said eyes being much larger than the pins, and hardenedsaddle pieces in the eyes and resting on the pins.

6. In a truck, the combination of the frame, a bolster hanger or stirrupprovided with eyes at its upper end, hardened saddle blocks itting insaid eyes at their upper porl tions vand provided with substantiallyiiat lower i aces, and hardened pins of much less diameter than the eyesand passing through the saine and into the frame.

7; In a truck, the combination of transonis, hanger brackets securedthereto, a bolster hanger or stirrup having its upper ends lying betweenthe transoms and brackets and provided with eyes, wear blocks tted insaid hanger at the upper edges of the eyes, pins ot less diameter thanthe eyes and passing through holes in the brackets and through the eyesand having reduced ends passing into holes in the transoms, and wearplates secured to the brackets and covering the ends of said pins.

In testimony whereof, I the said WILLIAM G. PRICE have hereunto set myhand.
